Updating my wii help please

Hey guys. So I'm back after quite a while. My wii has been sat in my sons cupboard for quite some time and has 4.1e on it. It was soft modded sometime last year. I'm looking to update it as much as I can to play all the latest games via the USB loader. Can someone give me some advice please?

You can start from Soft Mod With Homebrew Channel Installed.(Recommended)
It Does explain everything in that Guide What it will install and if you want to install the 4.1 system menu.... it is optional.
